Find an equation of the vertical line that passes through (1, 8).

Question

Quizplus · Accepted Answer

A vertical line has an undefined slope, meaning it is a straight line that goes straight up and down. Therefore, the equation of a vertical line passing through (1,8) will be of the form x=k where k is the value of x-coordinate of any point on the line. Since we know the line passes through (1,8), the value of k will be 1. Thus the equation of the vertical line passing through (1,8) is x=1.
